What condenser would work the best or be the most efficient for distilling HNO3? I believe Graham condensers have the most surface area, so would those work the best?

Grahams have the most surface area for their length, yes, but you do not need a highly efficient condenser for distilling nitric acid. A Liebig will do fine and will be cheaper.

Is it actually necesary for i.e. TNT or RDX to work with 99% HNO3 and H2SO4 or can it also be done with 80% ?
as far as i've tried it, it works fine for guncotton but nothing else.

A) I like my graham condenser, for about $15 more you get a condenser that I feel has more uses.

B) With 70% HNO3 and 93% H2SO4, use 3:1 (H2SO4:HNO3) acid mix, with 99%+ use a 3:0.75 nitrating mix.
